- Sumit will count odd no.s 1,3,5,7,9,11,13,...
Nitin will count no.s 32,31,30,29,28,...
let nth term be common then
1+(n-1)2=32+(n-1)(-1)
or 1+2n-2=32+1-n
or 2n-1=33-n
or 3n=34
or n=34/3(no integral value of x)
so no common terms at same time

- Ans: D
Explanation:
Nithin: 32 31 30 29 28 27 26 25 24 23 22 21 20…..Sumit: 1 3 5 7 9 11 13 15 17 19 21 23 25…Clearly it is seen that they never call out same nmber at the same time. - 10 years agoHelpfull: Yes(3) No(0)
